Which intervention is most appropriate for a nursing student to follow when applying personal protective equipment (PPE)?

Applying the gown before the mask is the correct intervention when using personal protective equipment (PPE). This sequence is crucial because it ensures that the mask remains uncontaminated. When putting on PPE, the gown acts as the first barrier to protect the healthcare worker from potential exposure to infectious agents.

By donning the gown first, healthcare workers prevent contaminants from clothing potentially coming into contact with the skin or other areas that would be protected by the gown. Additionally, if the mask is applied first, it can become contaminated during the process of putting on the gown, which may negate its effectiveness.

This sequence helps to maintain a sterile environment and reduces the risk of infection transmission, which is essential in healthcare settings where exposure to pathogens can occur. Following this proper donning sequence is part of standard infection control practices designed to safeguard both healthcare workers and patients.
